Oxygen Absorbing Sachets and High Barrier Sealable Transparent Oxygen Barrier Packaging Film
How To Work Out The Required Bag Size
Use the container size to calculate air content and determine the size and number of AGELESS pouches to be used. When oxygen is absorbed air volume decreases by up to 20%. As a result,there is a danger of products with protruding parts creating pinholes in thecontainer. To protect the containers from such protrusions use polyethylene foamed sheet or bubble-type cushioning material. When used in conjunction with vacuum packaging, AGELESS will generate lower t than atmospheric pressure in the container through its oxygen-absorbing functions. Create only a partial vacuum in the container to compensate |

Sealing Machine And Sealing Technology
Use a sealing machine that can create a hermetic seal

 Firmly grip both sides of the bag when sealing to avoid creases |
 Do not seal over foreign substances |
 Check for a complete seal. After cooling, pull on the seal from both sides. If it opens, the sealer was not hot enough |
To accurately decide the RP Agent size and number of pouches.
Calculate the air capacity of the barrier film bag in which the agent is to be enclosed.
Calculation method also applies to AGELESS Z and other types of sachet

| Total Volume (ml) | = W(cm) x L(cm) x H(cm) = 20 cm x 30 cm x 3 cm = 1800 ml |
Select RP Agent Pouches to be used
- To measure the total volume of a film bag, suppose that the bag containing an object is in the form of a square
or rectangular box. Take an approximate measurement of its length, width and height, using a rule. - Measure the weight of the object that is in the bag.
- For the specific gravity, use your judgement, based on the following: The specific gravity of iron is 7.9; copper is 8.9.
If the object is crusted with rust, its specific gravity is less than a pure metal.
Ignore the volume of the object contained in the bag if its calculation is troublesome. - 1 package of RPA-5 is required if the resultant air capacity is less than 500ml
2 packages of RPA-5 for an air capacity of 1 litre/1000 ml - Enclose an increased quantity of RP Agent when the earth adhering to the artifact is still wet immeadiately after excavation and temporary preservation is necessary.
- One package of RP-5 can absorb moisture equal to about 1 ml.
